Once you have configured the structured application, you can test XML roundtripping.
1)Create a valid structured proposal in FrameMaker.
2)Export the FrameMaker file to XML. To do so, select File > Save As and choose XML as the output format. If prompted, select the Proposal application.
3)Open the exported XML file in a text editor or an XML editor and verify that you have a valid XML file.
4)In an XML or a text editor, modify the file you just exported. You can also create an XML file that validates against the proposal DTD. Save the new XML file.
5)In FrameMaker, open the XML file. Verify that the XML file imports correctly and that formatting is applied automatically.
